Question

Solve the formula for the perimeter of a rectangle, with width w and length I,

Answer 1

Answer:

A. $\frac{P - 2w}{2} = l$

Step-by-step explanation:

Well in,

P = 2w + 2l

to solve for l we need to single it out.

P = 2w + 2l

-2w

P - 2w = 2l

divide everything by 2

$\frac{P - 2w}{2} = l$

Thus,

the answer is A.

Hope this helps :)

Answer 2

Answer:

( P -2w) /2 = l

Step-by-step explanation:

P= 2W + 2l

Subtract 2W from each side

P= 2W -2W + 2l

P -2W = 2l

Divide by 2

( P -2w) /2 = l
